I recently installed a Banks Exhaust system on my Titan and thought if anything I would cause the decrease in fuel consumption cause I enjoy hearing it so much. However after not stepping in on it for a while Ive noticed that my gas consumption has gone way down than before I put it on. Is this normal? I thought gas consumption would be near or perhaps a small bit better. Any ideas/comments.

Welcome aboard!

It's pretty hard to get great gas mileage with the Banks exhaust...it sounds so damn nice when you get on it. There is one rule for good gas mileage that has helped me, keep it under 2,000 RPMs, ALWAYS. With or without the Banks I didn't get great gas mileage unless I keep it under that line. Although, you feel like you are in the way on the road accelerating that slowly.

You may consider resetting the ECU to see if it learns differently with the new exhaust. It may buy you a little.

The decrease was to around 12. I didnt think it would be that dramatic but I guess I was wrong. Thanks for the input. I just didnt know if I had done something wrong.

Interesting that the brand of exhaust makes a difference in the mpg. I installed a JBA and haven't seen a decrease. Something to do with backpressure?

definately a good idea to reset your ECU after doing any kind of bolt-on aftermarket product install i.e. cat-back, headers, intake system - anything beyond that and you really want to get the truck retuned properly according to what you have done especially when you guys start getting into blower installs, doing head work, cam shaft ect ect - basically anything beyond the basic bolt on
